AllLights Puzzle
<< Back to Free Brain Games page

You need a Java-enabled browser to use this applet.


AllLights is a simple (but not easy) logic puzzle. The object of this game is to turn on all 25 "lights" on the board.

Instructions. Click the puzzle once to activate it. Clicking any square toggles its light as well as the lights of all horizontally and vertically adjacent squares on and off. Your goal is to click the squares in an order that results in all the squares on the board being lit.

As you play, the number of lit squares displays in the LightOn box. The number of dark squares displays in the LightOff box.

There is no time limit on the game. If you feel like you've messed it up too much to ever solve the puzzle, click the RESTART button to begin again.

This is a great puzzle for building concentration and brain power. Have fun!

Advanced Brain Training

Are you looking for a proven, scientific brain training program? If so, you might want to try Lumosity, the brain training service that I subscribe to.

I complete a quick, 10-minute Lumosity brain training session every morning. These training sessions exercise the different areas of my brain and prepare my mind for the day ahead. Over time, these sessions have sharpened my memory and other mental abilities in a significant and noticeable way.

A Lumosity brain training "session" consists of several mind-expanding brain games designed by the scientists at Lumosity and automatically selected for my individualized training program. Examples include Birdwatching, Monster Garden, Lost in Migration, and Spatial Speed Match, just to name a few.

Scientific studies show that Lumosity brain training measurably improves memory, attention, cognitive control, and processing speed. To help me track my own improvement, the "My History" section of Lumosity charts my brain's capabilities over time with easy-to-read graphs and Brain Performance Index (BPI) scores.

Lumosity is free to try. Complete one brain training session a day for two weeks, and I guarantee you'll be hooked!
